Unsubscribing from the Notices:

If you want to unsubscribe from the Notices,
please go to the notice invitation webpage, and
type in your site_name into selection "2. Modify an existing site".
Near the top of the webform page that pops up, click the box that says
"Tell the Adminstator to DELETE this site."
(It will send me an email saying you want your site discontinued.)

If you can't remember your site_name, just send me an email
with a few pieces of information that will help me identify
who you are and what site you belong to.
If you are part of a team operation,
then you need to be the Point-of-Contact person for that site.

Unsubscribing from the Circulars:

If you want to unsubscribe from the Circulars,
just send me a quick email listing your name
plus your Institutional/Project affiliation and email address that you received the Circulars.
(Note that some of these fields may have changed if you moved to a new institution after signing up.)
And I'll remove you from the Circulars list.
